G'day Vasili.
This should do it:
remLookupFwd :: (ReVars m t) => SimplRe t -> ReM m t (ReInfo t)
remLookupFwd re
= do fwd <- gets resFwdMap
let { Just reinfo = fromJust (M.lookup re fwd) }
return reinfo
The FiniteMap lookup operation took its arguments in the opposite order.
That's really the only problem here AFAICT.
Wow, this brings back memories. I wrote this module about ten years ago,
and I'm shocked that it's still getting use. I'd appreciate a copy when
you're done updating it for the modern era.
Cheers,
Andrew Bromage
